Strings Format Specifier In C ( %s ) The %s format specifier is used to print a sequence of characters, or astring, in C. When used with functions like printf(), it outputs the characters stored in a character array until it encounters a null terminator (\0). This specifier is fundament...

A format string vulnerability is another common error in the way in which user-supplied data is processed. It is common, in the C language, to use the *printf() functions to create and manipulate character strings. These functions take an argument known as the format specifier, followed by ...

In C programming language there isn't anyprintf()function converter to print in binary format. There is also not a binary conversion specifier in glibc (GNU Project's implementation of the C standard library) normally. But if we want to do so we have to create custom conversion types to ...
